Loneliness is considered a global public health issue because of its detrimental impact on physical and mental health but little is known about which interventions can reduce loneliness. One potential intervention is social prescribing, where a link worker helps service‐users to access appropriate support such as community activities and social groups. Some qualitative studies have identified that social prescribing may help to reduce service‐users’ loneliness. Given this, the British Red Cross (a third sector organisation) developed and delivered a national social prescribing service in the United Kingdom to support people who were experiencing, or at risk of, loneliness. Service‐users could receive up to 12 weeks of support from a link worker. A mixed methods study was conducted to understand the impact of the support on loneliness, and to identify the facilitators and barriers to service delivery. The study included: (a) analysis of quantitative data collected routinely between May 2017 and December 2019 (n = 10,643) including pre‐post analysis of UCLA data (n = 2,250) and matched comparator work to measure changes in loneliness; (b) semi‐structured interviews with service‐users, link workers and volunteers (n = 60) and (c) a Social Return on Investment Analysis. The majority of the service‐users (72.6%, n = 1634/2250) felt less lonely after receiving support. The mean change in UCLA score was −1.84 (95% CI −1.91 to −1.77) of a maximum change of 6.00 (decrease indicates an improvement). Additional benefits included improved wellbeing, increased confidence and life having more purpose. The base case analysis estimated a social return on investment of £3.42 per £1 invested in the service. Having skilled link workers and support tailored to individual needs appeared key. However, challenges included utilising volunteers, meeting some service‐users’ needs in relation to signposting and sustaining improvements in loneliness. Nonetheless, the service appeared successful in supporting service‐users experiencing loneliness.

We identified factors in the physical food environment that influence dietary behaviours among low-income dwellers in three African cities (Nairobi, Accra, Ho). We used Photovoice with 142 males/females (≥13 years). In the neighbourhood environment, poor hygiene, environmental sanitation, food contamination and adulteration were key concerns. Economic access was perceived as a major barrier to accessing nutritionally safe and healthy foods. Home gardening supplemented household nutritional needs, particularly in Nairobi. Policies to enhance food safety in neighbourhood environments are required. Home gardening, food pricing policies and social protection schemes could reduce financial barriers to safe and healthy diets.

This study developed, validated, and evaluated a framework of factors influencing dietary behaviours in urban African food environments, to inform research prioritisation and intervention development in Africa. A multi-component methodology, drawing on concept mapping, was employed to construct a framework of factors influencing dietary behaviours in urban Africa. The framework adapted a widely used socio-ecological model (developed in a high-income country context) and was developed using a mixed-methods research approach that comprised: i. Evidence synthesis consisting of a systematic review of 39 papers covering 14 African countries; ii. Qualitative interview data collected for adolescents and adults (n = 144) using photovoice in urban Ghana and Kenya; and iii. Consultation with interdisciplinary African experts (n = 71) from 27 countries, who contributed to at least one step of the framework (creation, validation/evaluation, finalisation). The final framework included 103 factors influencing dietary behaviours. Experts identified the factors influencing dietary behaviours across all the four levels of the food environment i.e. the individual, social, physical and macro levels. Nearly half (n = 48) were individual-level factors and just under a quarter (n = 26) were at the macro environmental level. Fewer factors associated with social (n = 15) and physical (14) environments were identified. At the macro level, the factors ranked as most important were food prices, cultural beliefs and seasonality. Factors ranked as important at the social level were household composition, family food habits and dietary practices. The type of food available in the neighbourhood and convenience were seen as important at the physical level, while individual food habits, food preferences and socioeconomic status were ranked highly at the individual level. About half of the factors (n = 54) overlap with those reported in an existing socio-ecological food environment framework developed in a high-income country context. A further 49 factors were identified that were not reported in the selected high-income country framework, underlining the importance of contextualisation. Our conceptual framework offers a useful tool for research to understand dietary transitions in urban African adolescents and adults, as well as identification of factors to intervene when promoting healthy nutritious diets to prevent multiple forms of malnutrition.

Visual cues such as plate size, amount of food served and packaging are known to influence the effects of portion size on food intake. Unit bias is a well characterised heuristic and helps to determine consumption norms. In an obesogenic environment where large portions are common place, the unit or segmentation bias may be overridden promoting overconsumption of both amorphous or unit foods. The aim of this review was to investigate the impact of offering unit or amorphous food on the portion size effect (PSE) in children aged 2-12 years. A systematic search for literature was conducted in Medline, PsycInfo and Web of Science in February 2018. A total of 1197 papers were retrieved following the searches. Twenty-one papers were included in the systematic review, of which 15 provided requisite statistical information for inclusion in a random effects meta-analysis. Increasing children's food portion size by 51-100% led to a significant increase in intake (SMD = 0.47, 95% CI: 0.39-0.55). There was no evidence to suggest that increases in consumption were related to food type (p = 0.33), child age (p = 0.47) or initial portion size served (p=0.14). Residual heterogeneity was not significant (p=0.24). The PSE was demonstrated in children aged 2-12 years when offered both unit and amorphous food items. The effect was not restricted by food type, child age or influenced by initial portion size served. Of the studies included in the meta-analysis between study heterogeneity was low suggesting minimal variation in treatment effects between studies, however, more research is required to understand the mechanisms of the PSE in preschool children. Future research should determine feasible methods to downsize portion sizes served to children.

Urbanisation in Ghana could be negatively impacting the state of food security, especially in economically vulnerable groups. Food supply, safety, and quality are all aspects of food security which could be impacted. We conducted a scoping literature review to understand the nature and magnitude of evidence available on the urban food security situation in Ghana. A literature search was conducted in Medline, CINAHL, Embase, Global Health, Scopus, Web of Science, Africa Wide Information and Google Scholar to identify relevant peer-reviewed and grey literature. 45 studies, mainly cross-sectional surveys/food samples analysis, met the inclusion criteria. The majority of studies were concentrated in the Greater Accra Region (n = 24). Most studies focused on food safety and quality (n = 31). Studies on supply and stability were, however, scarce. Qualitative research methods were uncommon in the included studies. The existing literature on food security are concentrated in two regions: The Greater Accra and Ashanti regions. Future studies exploring food security in urban Ghana should focus on exploring the lived experiences and perceptions of food insecurity and food stability by urban-dwellers using qualitative methods. The evidence suggesting that the safety/quality of foods sold in Ghanaian markets is poor should be a concern to consumers and policy makers.

Maintaining a high level of adherence to antiretroviral therapy (ART) is critical to limiting rapid viral replication, drug resistance, and viral transmission. However, ART adherence remains a major challenge in HIV/AIDS treatment success. This systematic review and meta-analysis was aimed to synthesize available evidence on adherence to ART among HIV/AIDS patients in Ghana.This review followed the preferred reporting item for systematic review and meta-analysis (PRISMA) criteria. A comprehensive literature search was done using five online databases (PubMed, Google Scholar, Medline, Africa Index Medicus, and Willey Online Library) from 25th- 30th April 2023 to identify potential studies. In addition, references of related articles were manually searched to further identify relevant studies. Search records were managed in Endnote library where duplicates were removed prior to screening. Studies were eligible for inclusion if they were conducted in Ghana, designed as an observational or experimental study, and explicitly measured adherence to ART, either as a primary or secondary outcome. Studies were excluded if the proportion or prevalence of adherence to ART was not reported.A total number of 126 potential studies were identified from the literature search. Of these, 14 met the inclusion criteria and were included in the Meta-analysis. The studies involved a total number of 4,436 participants. The pooled estimate of adherence to ART was 70% (CI: 58–81%). In subgroup analysis, adolescents and young adults had a lower adherence rate (66%, CI: 46–84%) compared with adults (70%; CI: 58–81%). Publication bias was not observed among studies. The pooled estimate of optimal adherence to ART among HIV patients in Ghana was lower than is recommended (≥95%) to achieve viral suppression. Adherence was lower among young persons living with HIV/AIDS. To achieve the United Nation’s Sustainable development goals and the UNAIDS “95-95-95” targets, there is a need to focus on improving adherence interventions among persons living with HIV/AIDS, especially among the younger cohort.
